Ideal alveolar ridge width and height allows placement of a natural appearing pontic, which provides maintenance of a plaque-free environment. The contour of a partially edentulous ridge should be thoroughly evaluated before a fixed partial denture is undertaken. Localized alveolar ridge defect refers to a volumetric deficit of the limited extent of bone and soft-tissue within the alveolar process. These ridge defects can be corrected by hard tissue and/or soft-tissue augmentation. A 30-year-old male patient was referred to the Department of Periodontology for correction of Seibert's Class III ridge defect in the lower anterior region. Granulation tissue/connective tissue present at the base of the defect was removed after elevation of full thickness flap. MucoMatrixX, an animal derived, collagen based soft-tissue graft was sutured to the labial flap and bone graft was placed into the defect. If a soft-tissue graft material could be used to replace the palatal grafts, then all the possible complications associated with donor site would be eliminated and above all periodontal plastic surgery and ridge augmentation would be better accepted by patients.
理想的牙槽嵴宽度和高度有利于放置外形自然的桥体,从而保持无牙菌斑环境。在进行固定局部义齿修复之前,应全面评估部分缺牙牙槽嵴的外形。局限性牙槽嵴缺损是指牙槽突内有限范围的骨组织和软组织的体积不足。这些牙槽嵴缺损可通过硬组织和/或软组织增量术进行矫正。一名30岁男性患者因下颌前部Seibert III类牙槽嵴缺损矫正被转诊至牙周病科。在掀起全厚瓣后,切除缺损底部的肉芽组织/结缔组织。将一种动物源性、基于胶原蛋白的软组织移植物MucoMatrixX缝合至唇侧瓣,并将骨移植物植入缺损处。如果能用软组织移植物材料替代腭部移植物,那么与供区相关的所有可能并发症都将消除,最重要的是,牙周整形手术和牙槽嵴增量术会更容易被患者接受。
